The general form for the equation of a circle centre (xo, yo) and radius r is:
(x - xo)2 + (y - yo)2 = r2
Which can be rearranged into:
x2 - 2xox + y2 - 2yoy = r2 - xo2 - yo2
So a circle with centre (4, -1) and radius 8 has equations:
(x - 4)2 + (y + 1)2 = 64
x2 - 8x + y2 + 2y = 47

What is the equation of the circle with a center of 2 and 1 and a radius of 20?
The equation of a circle can be expressed in the standard form ((x - h)^2 + (y - k)^2 = r^2), where ((h, k)) is the center and (r) is the radius. Given the center at ((2, 1)) and a radius of (20), the equation becomes ((x - 2)^2 + (y - 1)^2 = 20^2). Simplifying this, we have ((x - 2)^2 + (y - 1)^2 = 400).
